You should worry instead about the effects of excreted pharmaceuticals and neo-nicotinoid pesticides on wildlife, excess fertilizer runoff on coastal ecosystems, and ocean acidification from CO2 dissolving to produce carbonic acid, making sea life unable to fix calcium for shells, destroying the underpinnings of the food chain and the whole ocean ecosystem. Oh, and global climate disruption.

We have no need to borrow imaginary trouble, we are making plenty of actually real trouble already.
